Abstract: Engineering application of the collaborative optimization technology is studied through an example-the design optimization of the working device of a hydraulic excavator.The technology route of structurally static and dynamic collaborative optimization is studied, and some useful strategies are put forward to deal with technology difficulties during the parameterized FEA modeling stage, the collaborative optimization modeling stage and the collaborative optimization stage.Based on the distributed collaborative optimization strategy and structurally dynamic and static collaborative analysis strategy, the design optimization process is completed automatically under Internet circumstances, and a satisfactory optimization result is obtained.

Key words: structural optimization, working equipment of hydraulic excavator, collaborative optimization
